Ultimate Guide To Folding@home

What is gromacs?

Gromacs is the new folding core (FAHcore_78.exe) GROMACS provides extremely high performance compared to all other programs. For some calculations, gromacs affords benefits over the current code in FAH (the current code is based on Jay Ponder's Tinker), especially a great speed increase (perhaps up to 10x-20x). This will substantially increase the power of FAH for many calculations.

some ppl say that it actually gives you more points as well...so its a WIn WIN! situation :D

Streaming SIMD(Single Instruction Multiple Data) Extensions

Processors & applications that do not use SSE process one data element in one instruction, a processing style called Single Instruction Single Data, or SISD. In contrast, processors having the SIMD capability have the ability to process more than one data element in one instruction. In other words the processor can work harder with the same two hands (if you get the metaphor). Using SSE requires support from the application, the operating system & the CPU.

Processors that have SSE are as follows..

Athlon XP
Duron 1 GHz & above (morgan core)
Pentium 4
Pentium 3
Celeron 566 mhz & above (coppermine & tualatin cores)

Processors that do not have SSE are as follows..

Duron 950 & below (spitfire core)
Athlon (K7, K75, & Thunderbird cores)
K6-3
K6-2
Celeron 533 MHz & below
Pentium 2
Pentium
All Via/Cyrix CPU's

Anything released before the processors listed of course does not have SSE.

Any version of Windows after '98 supports SSE (95' may just not sure). Any newer Linux distro should have support as well.

The Gromacs core also uses AMD
 
Ahh, thanks for clearing that up for me Lynx, it just seemed rather odd that it was taking longer to work on a faster processor. lol

After the first WU, they seem to be going much faster now. The Gromac tags really do help alot!

Finally.

20,000 points.

Watch out, VB, I'm after you. ;)

I'll even let you have a chance. I have taken one of my machines offline. :)
 
I'm sure theres an easier way to explain this prog. :blink:

To much abracadabra in this thread to me. Thanks to Slinger i had it working in a few minutes, while reading this thread only gave my headaches.

You have got to remember that theres a lot of foreign non geeks on this board who would like to contribute as well.

Just my 2 cents :)
